Hugh Hefner's Son Cooper Is Engaged to The Vampire Diaries' Scarlett Byrne!

The Playboy founder's son is going to be a married man! Cooper Hefner, son of media mogul Hugh Hefner, is engaged to The Vampire Diaries actress Scarlett Byrne.

Cooper announced the news on his Instagram, where he posted a photo collage of him with his brand-new fiancé, whom he's dated for almost two years. "To many more adventures with this lovely lady," he captioned the above photo.

As for the Hef? He tweeted out his congratulations to Cooper, his son he had with his second wife, former Playboy playmate Kimberly Conrad. "Sending love and congratulations to my son Cooper and his fiancé Scarlett on their engagement," he wrote.

Seeing as the elder Hefner is something of a newlywed himself — he married playmate Crystal Harris in 2012 — we're sure he has plenty of wedding-planning and marriage advice to pass along. Not only that, but perhaps he'll suggest the Playboy Mansion as a wedding venue! After all, stranger things have happened.
